摘要

我国小拱棚建设机械多采用人工投杆和机械栽植,建设效率和机械化程度低。因此,我们设计了一种棚杆自动送杆装置,实现了自动分单、有序输送、及时落杆。以棚杆投料合格率作为回归模型的评价指标,采用三因素、三级试验设计,将取料环速度、落棚杆高度和取料环间距确定为主要影响因素,在试验中分别得到 23.94 r/min、408.799 mm 和 1350 mm,大棚合格率为 95.36%。使用 Design-Expert 13 进行方差分析,确定了最佳参数组合。在使用台架调整和最佳参数组合进行的试验中,测得的平均大棚合格率为 94.23%,试验值和理论优化值之间的相对误差为 1.13%。这证实了优化参数组合的可靠性。在现场验证测试结果中,拾取卡环速度为 24 r/min;大棚杆下落高度为 410 mm;拾取卡环间距为 1350 mm;俯仰率为 95.37%,与理论优化值相比误差为 0.01%。样机运行性能稳定,满足设计要求。

Design and Test of Automatic Feeding Device for Shed Pole of Small-Arched Insertion Machine
China’s small-arched shed-building machinery mostly adopts manual pole casting and mechanical planting, which have low building efficiency and mechanization. Therefore, we designed an automatic feeding device for shed poles to realize automatic single separation, orderly conveyance and timely dropping of poles. Considering shed pole-pitching pass rate as the evaluation index for the regression model, we adopted a three-factor, three-level experimental design and established the speed of the reclaiming ring, height of the falling shed poles and reclaiming ring spacing as the main influencing factors, obtaining 23.94 r/min, 408.799 mm and 1350 mm, respectively in experiments with a trellis qualification rate of 95.36%. Design-Expert 13 was used to perform analysis of variance and determine the optimal parameter combinations. The average measured trellis qualification rate in tests with the bench adjusted and the optimal parameter combination was 94.23%, with 1.13% relative error between test and theoretical optimization values. This confirmed the optimal parameter combination’s dependability. In field verification test results, pick-up card ring speed was 24 r/min; height of trellis pole drop, 410 mm; pick-up card ring spacing, 1350 mm; and pitching rate, 95.37%, obtaining 0.01% error compared with theoretically optimized values. The prototype operational performance was stable and satisfied design requirements.
